Application filed November 30, 1921.

.lie it known that l. Nini. itixclxxics. a citiweio't the Vnited States. and a resident oil the cit'v of Chicago. countv ot took. and State oi Illinois. have invented certain new and uset'ul improvements in Automobile Bumpers. ot' which the tollowinpr is a speciiicatioi'i.

invention relates to improvements in bumpers. especially adapted tor `use on automobiles and the like, the object ot the invention bein;r to provide an improved construction ot' this character capable ot economical production and highly efiicient in use.

Other objects will appear hereinafter.

'lhe invention consists in the combinations and arrangements o't' parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanyinp` drawings forming" a part of this specification, and in wli'ch,

Fiezjvl is a partial top plan view showing a bumper embodying` the invention and secured in position ot' use on the front of an ordinary automobile,

Fig. 2 is an enlarged section taken substantially on line 2 2 oi" Fig. 1.

Fig. 2i is a rear tace view ot a clamping' block employed in the construction,

Fie'. -l is an end view corresponding with Fig. 3. i

Fig. 5 is a rear view ot a bumper bar employed in tbe construction.

Fig. (i is a top plan view ot the saine7 and Fig". 7 is a view taken substantially on line 7 7 ot Figi. 9.

rl`he preferred torni o't construction as illustrated in tbe drawings. comprises a steel bar S bent into a shallow curve as shown. and havingY securingr arches 9 struck Vtrom each end thereof and extended rear 'ardly and shaped into substantiaily arch At'orm as indicated.

A mounting' bracket 10 is provided for securing;VV each ot the arches 9 to the corresponding side bar ot an automobile. Each of the brackets itl is formed trom a single strip oi steel bent as indicated into substantially triangular form, forming a 'iront vertical side l1. a down faidlyY and rearwardly extending' lip 12 at the lower apes; of the triangle. an upwardly and rearwardly inclined side 13 acla'pted to rest, with the lip l2, against the sico liar 14 o'lE tbe automobile.

Specification of Letters atent.

Serial No, 518,750.

The remaining side ot the triangle is formed oi the overlapped ends 15 and 16 of said lstrip. said ends lo and 1G being overlapped and inwardly bowed to correspond, and as indicated. to torni the said'side of said triangle into a spring. substantially tlshaped clamp or clevis 1T is provided and utilized as indicated to secure each of the brackets l() to the corresponding side bar l: ot' the automobile as shown.

Clamping' heads 18 are also provided to rest against the front sides 1l of said brackets. each cianipinpr head beingr provided with perfor-ations 19 at its ends tor the passage oi' securing bolts 2O and with guide lugs 2l. sliding in a vertical slot 22 in the front side ll of the corresponding bracket 10. Each' clampingT head 18 is also rovided with a transverse slot 23 adapted) to engage the corresponding securing arch 9 to clamp the same against the corresponding side 11. Cooperating with each clamping.r bead 18 is a plate 24 adapted to tit against the rear side oi each bracket side ll and also perforated tor the passage of the bolts 20. and whereby the bumper bar S may be readily and-adiustably secured to the front of the automobile. By this arrangement a simple and etl'ective flexible spring mounting is provided ior each end ot the bumper bar.

The construction disclosed, constitutes a simple and effective one for the purpose, which ,is capable ot economical production and highly ze'fiicient in use.

Tshil'e i have illustrated and described the preferred "form of construction for eariving my invention into effec/t. this is eapable oi variation and modification without departingv from the spirit of the invention. l. therefore. ilo not wish to be limited to the precise details ot construction set forth. but desire to avail myself of such variations and modifications as come within the scope ot' the appended claims.

-laving described my invention, what claim as new and desire to secure by Letters Patent is:

l. bumper comprising a bar having a. portion struck therefrom and extended rearwardly to torni a securing member for said bar. substantially as described.

2. A bumper comprising a bar having a portion struck therefrom and extended rearwardly and shaped into an arch to form a securing and stitiening member for said bar, substantially as described.

Gli

3. A bumper comprising a bar having two portions struck from the ends thereof and extended rearwardly to form securing membeis for said bar, substantially as described.

4. A bumper comprisingr a bar having two portions struck from the ends thereof and extended rearwardly and shaped into arches to form securing and stiffening members for said bar, substantially as described.

A bumper comprising'a bar having a portion struck therefrom and extended rearwardly to form a securing member for said bar; two flexible brackets; and means for securing said brackets to said securing member and the frame of an automobile or the like, substantially as described.

(i. A bumper comprising a bar having a portion struck therefrom and extended rearwardly and shaped into an arch to form a securing and stiffening member for Said bar; twoV flexible brackets; and means for securing said brackets. to said securing member and the frame of an automobile or the like, substantially as described.

7. A bumper comprising a bar having two portions struck from the ends thereof and extended rearwardly to form securing members for `said bar; two flexible backets; and means for securing said brackets to said securing members and to the frame of an automobile or the like, substantially as described.

8. A bumper comprising a bar having two portions struck from the ends thereof and extended rearwardly and shaped into arches to form securing and stiffening members for said bar; two flexible brackets; and means .for securing said brackets to said securing members and to the frame of an automobile or the like, substantially as described.

9. A bumper comprising a bar having two portions struck from the ends thereof and extended rearwardly and shaped into arches to form securing and stifl'ening members for said bar; two flexible brackets in substantially triangular form; a clamp securing each bracket to the frame of an automobile; and a clamp adjustably securing each bracket to the corresponding securing arch member of said bar, substantially as. described.

10. Tn a bumper of the class described comprising a bracket formed of spring ma- .i

terial of substantially inverted triangular shape. having one side fastened in position, the other side thereof having a bumper mounted intermediate its ends, substantially described.

f ll. bracket of the class described formed of-a single strip of spring material bent into substantially triangular form, the ends of said strip being correspondinrly inwardly bowed and overlapped to form t spring side to said bracket, substantially as described.

12. A bracket of the class described consisting of a single strip of spring material bent into substantially triangular form, a rearwardly and downwardly turned extension being formed by one of the apices of said triangle and the ends of said strip being overlapped and inwardly bowed to form th'e side of said triangle opposite said i extension. substantially as described.

13. In a bumper of the class described comprising a bracket -formed of a single strip of spring material bent into substantially inverted triangular form, the ends of said strip being correspondingly inwardly bowed and oyerlapped to form a spring base for said bracket; means for securing one side of said bracket in position; and a bumper mounted on the opposite side of said bracket intermediate its ends, substantially as described.
